The Postnatal Development of the Human Cerebral Cortex

This book, which is clearly printed and beautifully illustrated, is a masterpiece of work. The study is being carried out in the Department of Anatomy of the Boston University School of Medicine and the Department of Pathology of the Harvard Medical School in the Children's Hospital and the Infants' Hospital. In the introduction Conel states that the investigation is intended to be a general survey of the postnatal development of the nerve cells in the normal human cerebral cortex. This volume describes the state of development of the neurons in the cerebral cortex of the nine month fetus immediately after birth. All the brains used were obtained from necropsies done within twenty-four hours after death. Great care was used in accepting brains for the study. Six brains were used, four from white male and two from white female infants. Ten per cent formaldehyde was used as a fixing agent. Celloidin
